CU 4.12Mirrors and Reflection
The child sees that a mirror bounces light back, makes a spot of light move on the wall, and finds shiny things that reflect.

Look into the mirror together. Raise a right hand and notice the reflection raises the hand on the same side.
- 2
Hold the letter card in front of the mirror: 'The mirror shows it backward.'
- 3
Darken a corner. Shine the flashlight onto the mirror and find the spot of light on the wall.
- 4
Tilt the mirror slowly and watch the spot move. Invite the child to aim it at a chosen place.
- 5
Test each object in the basket: 'Can I see myself? Does it bounce the light?'
- 6
Sort into 'reflects clearly' and 'does not reflect clearly'.
What catches the child’s eye
- The spot of light darting across the wall with a tiny tilt of the mirror
- A single toy turning into many copies between two mirrors
Extensions, easiest to hardest
- Stand two mirrors together like an open book with a toy between and count the copies
- Look at the front and back of a spoon and compare the reflections
- Write a short name backward so it reads correctly in the mirror
- Look for reflections in puddles and windows outside
Control of error
The mirror and the light show the result: the spot lands where it is aimed or not, and the child can see whether a surface shows a clear picture.
Ready to move on when the child…
- Aims the light spot at a target
- Says that a mirror bounces light back
- Sorts the materials correctly
Guide note
Use acrylic mirrors only, never glass. Children never reflect sunlight or a flashlight into anyone's eyes.
